awk comands inside m4 macros

[Chris Coleman]

Hi,

I'm sorry for asking what must be a trivial question to this list, but 
I've used up all my ideas, and am relatively new to autoconf and m4.

If from the comand line shell sh I excecute the comand:

sh-2.05b$ boost=1.32.0; echo $boost | awk -F. '{print $1}'
1

Then I get the expected result '1' echoed to the screen., $2 => 32 and 
$3 => 0

When I place the same in a configure macro as below, run my bootstrap 
script, and then excecute the resulting configure script 
($boost_min_version == 1.32.0):

WANT_BOOST_MAJOR=`echo $boost_min_version | $AWK -F. '{print $1}'`
echo $WANT_BOOST_MAJOR

$1 => 1.320
$2 => 1.32.0
$3 => gives the below error:
awk: syntax error at source line 1
context is
       {print >>>  { <<<
awk: illegal statement at source line 1
awk: syntax error at source line 2

What have I missed when transfering a command from the comand line, into 
my configure scripts like this?

Many thanks
Chris
